It has long been known that happiness depends on many different life circumstances.

Now scientists have developed a mathematical equation that can predict momentary delight. They found that participants were happiest when they performed better than expected during a risk-reward task. Brain scans also revealed that happiness scores correlated with areas known to be important for well-being. The team says the equation, published in PNAS Journal, could be used to look at mood disorders and happiness on a mass scale. It could also help the UK government analyse statistics on well-being, which they have collected since 2010.

Every day it seems like we feel hundreds of different emotions – each nuanced and specific to the physical and social situations we find ourselves in.

According to science, it’s not that complicated by a long shot. A new study says we’re really only capable of four “basic” emotions: happy, sad, afraid/surprised, and angry/disgusted.

But much like the “mother sauces” of cooking allow you to make pretty much any kind of food under the sun, these four “mother emotions” meld together in myriad ways in our brains to create our layered emotional stews.

Robert Plutchik’s famous “wheel of emotions” shows just some of the well known emotional layers.

In this post we’ll take a close look at each of the four emotions, how they form in the brain and the way they can motivate us to surprising actions. Read More
